Science definitions for glutathione
[ glōō′tə-thī′ōn′ ]
A polypeptide consisting of glycine, cysteine, and glutamic acid that occurs widely in plant and animal tissues. It is important in cellular respiration in both plants and animals, and serves as a cofactor for many enzymes. It is a major protective mechanism against oxidative stress. For example, it protects red blood cells from hydrogen peroxide, a toxic byproduct of certain metabolic reactions.
